6 months ago All L handles turn to fasten an adjustable portion of the lathe.
Use a hammer or drill to get one side as far onto the four teeth spindle as you can.
Turn right side spindle tighten on from the right.
This is a very weak lathe. Be sure to check all attachment points and secure to spindle with more than friction. Go slow at the beginning. The direction of spin makes the object fly away from you mostly.
